Classification
While BR has the chemical structure of 1,4-cis-Polybutadiene, SBR is the styrene/butadiene copolymer and is produced both in emulsion and in solution. Many grades of SBR are available on the market, differing in their styrene content (ranging from 23.5% to 45%) and oil extender content.

Polymer Type
SBR and BR are commonly used blended together or with NR, combining the good mechanical properties of SBR with the excellent abrasion resistance of BR.

Applications
In addition to their widespread use in tires, SBR and BR are also widely used in technical products where high abrasion resistance is required (such as conveyor belts), and where chemical resistance and temperature resistance requirements are not high.
